Rookie Mistake...
man, at this point it almost seems like you're lucky to get the car back and (hopefully) all the pieces.
the money aspect of it is a real kick in the sack, but i suppose you could do an easy 10k in bad publicity and he could mysteriously catch several grand worth of flats over the next few years.
(i mean that would just be terrible if he caught two flats on the morning he had to be in court)
but you've got a lawyer, so let it ride and hopefully he can make you whole or at least make that little shitbird's life more difficult.
